Cast cover



FIG. 1 is a front view of my new design for a cast cover;

FIG. 2 is a rear view thereof;

FIG. 3 is a left side view thereof;

FIG. 4 is a right side view thereof;

FIG. 5 is a top view thereof;

FIG. 6 is a bottom view thereof; and,

FIG. 7 is an isometric view thereof in use.

The broken line showing of an arm in a cast is included for the purpose of illustrating environmental structure and forms no part of the claimed design. 

I claim the ornamental design for cast cover, as shown and described.
